Reaction Steps

Compound 99c was prepared in the same manner as 2,2-bis-hydroxymethyl-but-3-enoic acid tert-butyl ester using 2,2-dimethyl-5-vinyl-[1,3]dioxane-5-carboxylic acid ethyl ester instead of 2,2-dimethyl-5-vinyl-[1,3]dioxane-5-carboxylic acid tert-butyl ester in 78% yield. 1H NMR (300 MHz, d6-DMSO) 61.17 (t, J=7.0 Hz, 3H), 3.59-3.71 (m, 4H), 4.06 (q, J=7.0 Hz, 2H), 4.65 (t, J=5.6 Hz, 2H), 5.13 (d, J=18.5 Hz, 1H), 5.15 (d, J=10.5 Hz, 1H), 5.80 (dd, J=18.5, 10.5 Hz, 1H). LCMS (m/z) 197.1 [M+Na], Tr=0.96 min.
